I know that there are probably specific rules about having to go through a retailer, but would it be possible to arrange a bulk buy in the US as well? Not that I would want to cheat DNNA out of the cash, but that we could arrange for the quantity needed in one large order, likely without the retail markup or sales tax, and then be able to redistribute within the US?

Again, I do not know if this is possible, based on DNNA's distribution agreements, but possibly worth asking about.
